🧠 What if we could detect Alzheimer's risk years before symptoms start?

We actually can—and we’re getting better at it every day.

There are now brain health tests that look at early warning signs, like:
✔️ Abnormal tau protein
✔️ Changes in amyloid levels (Aβ42/40)
✔️ Markers of brain inflammation (like GFAP)

But what’s really exciting? Scientists are also looking at lipid markers—yes, the way our brain processes cholesterol might tell us even more.

One of these markers is called desmosterol. Lower levels of it may show up early in people at risk—especially those with a gene called APOE4, which affects how the brain handles fats and increases Alzheimer’s risk.

🧪 Not yet ready for routine clinical use, but definitely one to watch as we move toward precision neurology and earlier, more personalized interventions.

💡The takeaway? Brain changes can begin long before memory loss. The earlier we know, the more we can do.
